OK Doug, yet to buy the cable, but done the 2nd throttle thing on PC only of course, but for clarification it semsto me that when I upload this map to the ECU will it give it the map for my decat system with the 2nd's kept open, or from your description will it be 2nd's only.
It will be 20219 but with the 2ndaries 100% open. It's the TOR/cat bypass tune with secondaries 100% open
There's also a thread on this site:

Ask Tom-Hamburg for this tune: 20050DynoFinalMap_TOR_CatBypass_Decel.hex
This is a custom tune for TORs/cat bypass with some fiddling to reduce decel popping. For this, you need to uncheck the O2 sensor option in TuneECU, then download. Also, fix the speed, and put the speed limit to 300 mph.
